Interactive API reference for the JavaScript Float64Array Object. Float64Array is similar to an Array where each item is a 64 bit (8 byte) floating point number (the same as the standard Number type).
Interactive API reference for the JavaScript Float32Array Object. Float32Array is similar to an Array where each item is a 32 bit (4 byte) floating point number. Float32Arrays cannot change size after
This solution depends on simultaneous adoption of new functionality across browsers. If the Chrome browser implementedArray.prototype.removefirst, then all other browsers would still fall back on the home-grown implementation which may do something entirely different. For the same reason Prototype.js wou...
lastIndexOf: The lastIndexOf() method returns the last index at which a given element can be found in the array, or -1 if it is not present. The array is searched backwards, starting at fromIndex. lastIndexOf: The lastIndexOf() method returns the index within the calling String objec...
